Beauty Mark It! The Best Tooth Whitener

Having white teeth is one of those small things that can make a big difference in your appearance. And it's not just about improving your appearance (although, of course, that helps.) When you're happy with your smile, you'll smile more — and that sends a message of confidence.

But since tea, coffee, soda, and cigarettes all stain teeth, you'll have to whiten them to get a brighter smile. This is where I turn it over to you. What do you use to get that sparkling smile? Do you have a special toothpaste you love, or maybe you're dedicated to whitening strips? Or maybe you're hardcore with the bleaching paste and retainers?

Share your choices by bookmarking items from around the web and tagging them with the phrase white teeth. I'll feature your favorites here next Tuesday.
